Hi Samantha, Welcome to the forum. I am sorry you are having such a hard time. It sounds very upsetting what you are experiencing. It sounds like there may be some psychological issues going on coming up in the form of nightmares so you may want to talk to your doctor about it and possibly find a therapist to talk to. Unresolved past trauma can find it's way into our dreams even trauma we don't remember. I see you are only 14. Have you talked to your parents about this? You might want to try posting your comment in the Teen Depression forum,
http://www.medhelp.org/forums/Teen-Depression/show/185 or in the Sleep Disorder forum,

as well maybe the PTSD forum if you have known trauma,
http://www.medhelp.org/forums/PTSD---Post-Traumatic-Stress-Disorder/show/316. This said, I think it important that you tell your parents what is going on and see if you can get in to see a therapist about it so you can sort out the dreams and hopefully resolve it. Take care. Keep us posted on how you are doing.
